While it’s true that Germans might value their privacy more than others, the fediverse is incredibly niche and most people either use the big corpo apps or nothing. Also lemmy is not anonymous, at most maybe pseudonymous.
I really don’t get point 2. Isn’t being a member of the fediverse rather advanced? But also how are Germans technologically behind regarding common personal life?
I’m Gen Z and almost all of my friends know English well enough to have a conversation online. Granted, I work in IT, but not all of my friends are technology people and this still holds.
Counterpoint: I think Germany is just a rather big Western country with many technologically interested people and people who value fediverse ideals like being free from corporate influence. There are dozens of us!
